Il t) HERBERT SCOTT BOVIMAN, OF ST; JOE, INDIANA.

fcALnNnAn.

To all whmu t Illi/u z/ Coface/rn.'

Be it known that l, l-lnnnnn'r Soo'r'r Bon/1 MAN, a citizen of the United States, residing' at St. Joe, in the county of De Kalb and State oi' indiana, have invented new und useful lmprtwements in Calendars, ot which the following is a specitication.

-Tne .invention relates to calendars. object is to providea lnovel 4torni ot' calendar which is perpetual in its nature and which is operable to automatically indicate the day ot the wech upon which any se lected day of any year `tells.

rihe inventionconsists ot' the novel combination and arrai'igemcnt ci' parts illustrated in the accompanying drawings in which- Figure l' is affrontA elevational view ci the calendar; Fie. 2 a cross-section on line 2-2 ott Fig. i; Fig. San elevational view oi a traction orf the week day indieating chart and operating mechanism.; Fig. et an elevational viewotthe month indieating.,T chart and day indicatorniechanism, and Fig. 5 an elerational view'ot the month table.

Referringl to the illustrative embodiment oi the invention, l represents a suitable case, the trout 2 ot which is preferably inclined and has vloi'ineul therein an opening o ot suiiicien; size to aitliord vision there-` through ot the table :4l the days ot a month termed on a slide or plate 5 slidably mounted in the slides suitably fixed within the case. Above this opening at 7 the days of the week are imprinted or otherwise .shown upon the `iront., the names being spaced transversely in accordance with the transverse spacingv of the vertical rows ot the figures on the table 4. A vertical slot 8 is also termed in the iront behind which is slidahly mounted a slide or plate U upon .vhich the names ot the months are imprinted or otherwise shown in setuurnce, the slot being ot a width suilicientto expose any one oit the naines or the months `on the plate 9.

A horizontal slot 10 is formed in the front above the slot 8 behind which is a revolubly mounted roller 1l to which is attached one end oit a chart 12. A hand wheel or disk 13 is secured to the roller und projects forwardly through a slot lil formed in the front 2 by which the roller may be rotated. The other end ot the chart is secured to a second roller 15 revolubly mounted in the case and the two rollers are ItsV mename fneaAprn ro, 1925. serial No. 22,233.

Voperatively connected by the belt or cord .16 so that the chart may be wound from'one roller upon the other for exposing any one of thehorizontal rows of indicia 17 im.- printed or otherwise formed on the chart.

Each row ot' imprinted matter von the chart l2 comprises numerals, representing a year, and twelve names oi the week days representingV respectively the days oi" the week upon which the first daysof the month oit that year fall'. The columns of Anaines oitlthe week days are spaced apart trans# versely in accordance with the spacing oi' the names'oi the months on' the plate 9:

Any number oi years may be provided `for on the chart. l l

A slot 1S is `formed in the lower portion ot the trontZ through which project' the ends of two bars 19 andQO suitably formed at their vouter ends forconvenient manipulation. l The inner end of.' the bar lIQi's leent upwardlyv and attachedto or itis a part of the slide 5. The slide maybe moved to the right or lett by the bar` in order to position the figure l oi4 the'table `under the correct day in the heading 7.. The bar 20 i is similarly connected to or Vit 4is par-t of the plate or slide 9 and serves as a means forni'oving the said slide to the right or lett to expose the desiredmonth. A pointer 22 is secured to or itmay bea part of the slide 9 and projects upwardly and out*- wardly through the slot 10. It' is sol positioned on the slide 9 that it will register with the exposedindicia in the column :on the chart Jfor the month exposed through the slot` 8, it being evident that the iirs'.

column of letters on the lett ot the chart indicates the days of the week upon which the lirst day oi January in each year Yfalls, the second column being tor February, the third for March, etc.

The figures on the table slide 5 are so arranged in columns and rows that a complete month will be exposed through the opening 3 no matter on which day of the week the first day oi' any month Jfalls.

Preferably a transparency ,'23, such as glass 'or Celluloid, is iiXed in the case to cover the front side with the exception oiV the slot 18. The outer 'faces of the slides and the chart are thereby maintained in clean condition.

To operate the calendar thel rollers areoperated to cause the selected year on the chart ico to be exposed through the slot 10. The slide i slide accordingly.

` procedure just described.

9 is then moved in pioper direction until the name of the selected month appears behind the slot S. Since the pointer is carried with this slide it, at the same time, is caused to register with the name of the first day of that selected month appearing on the chart through the slot 10. The slide 5 is then moved in proper direction until the numeral l registers with the same day of the week found in the row 7. The calendar is now set for the month. If the user desires to learn on :what day of the week any future date during that year falls he adjusts the month indicating slide to the proper month, notes the first day of that month on the chart as indicated by the pointer and sets the table The datey is then found on the table and the week day i'ead in the row 7. If the date is in any other year, within the limits of the chart, he first sets the chart to that yeai1 and then` follows the The calendar, therefore, is not only for current use but is usable not only for a long period of years, but also to determine future or past dates when the week days are known, or future or past week days when the dates are known.

It is apparent that various means and methods of operating the chartand the slides may be used, the means therefore described and illustrated being illustrative only.

What I claim is:

l. A calendar comprising a case having a plurality of openings in its front side, a table of numbers representing days movably mounted behind oneV of the openings, a month indicating member movably mounted behind another of said openings, a` chart movably mounted behind another of said openings and having thereon a column of figures representing a plurality of years and a plurality of columns of indicia' representing the days of a week, one column foreach month of a year, each indicia of a horizontal row representing the week day naine of the first day of the column month of the year designated in said row, and a pointer carried by the month indicating member and cooperating with the chart to v automatically indicate the week day name of the first day of any month and year as de` termined by the chart and the month indicating member.

2. A calendar comprising a case having a plurality of openings in one of its sides, a pair of rollers revolubly mounted rearwardly of one of the openings, a chart secured at its opposite ends to the rollers respectively, the chart having thereon a column of numerals designating a plurality of years, and also a plurality of columns of indicia designating the names of the days of a week, one column foi each month of a year, the indicia in the horizontal row with any year designating the week day names of the first days of the months of that year, means to rotate the rollers in either direction to cause a selected row of year and week day indicia to be eX- posed through said opening, a movable slide having thereon the names of the months of a year. in consecutive order adapted to be selectively exposed through another of said openings, a pointer responsive tothe movenient of the slide to indicate the week day name on the chart of the selected month and year, the names of the week days being formed on the said slide in order and above another of saidopenings, and a movable e
